It's Chicago West: Kim and Kanye name third child

Kim Kardashian West and Kanye West, who announced their third child is called Chicago, already have two children: daughter North, four, and son Saint, two

Kim Kardashian and rapper Kanye West have called their third child Chicago, the reality star announced Friday, opening the floodgates to hefty doses of mockery and consternation on social media.

Kardashian West announced the name on her app, later suggesting the little girl already has a nickname. "North, Saint and Chi," she tweeted to her 58.4 million followers -- to be pronounced "Shy" the 37-year-old later clarified.

The couple already have daughter North West, four, and son, Saint, two.

Kardashian West and West, 40, who married in a lavish ceremony in Italy in May 2014, have been dogged by rumors of trouble in paradise recently amid gossip-press speculation that their marriage is on the rocks.

Celebrity website TMZ said the couple chose a surrogate after Kardashian suffered from a serious condition in which the placenta becomes too deeply attached to the wall of the uterus during her second pregnancy, making a third pregnancy too risky.

TMZ said the couple paid the surrogate $45,000, banning her from smoking, taking drugs, hot baths, dying her hair and eating raw fish during the pregnancy.
